Microsoft will release up to 10 test updates tomorrow to computers running the near-ready version of its upcoming operating system, Windows 7.

The company will spit out the updates over the coming week to users testing the Release Candidate version of Windows 7.

This is the second time Microsoft has decided to deliver dummy updates for testers of its OS, which is widely expected to land in autumn this year.

In February Redmond released five bogus updates to probe the forthcoming operating system’s updating abilities.

The latest updates will not deliver any new features or bug fixes to the RC build, but instead will replace existing system files with exact duplicates to “verify the update infrastructure to ensure that when we need to release real updates, the process will run smoothly,” according to the Microsoft Update team.

MS has said that most of the updates will install automatically, but a few will need to be installed manually. ®
